  <h2>
   Behavior
  </h2>
  <p>
   The Poke Tool is for manipulating the current values associated with
components. The precise behavior of the Poke Tool varies depending on
which component is clicked; this behavior is documented in the `Poke
Tool Behavior' section of each individual component.
The following components all have support for the Poke Tool.

  <p>
   Also, clicking a wire segment using the Poke tool displays the value
currently carried by the wire, as described on the
   <a href="wiring.html">
    Wiring Tool's page
   </a>
   .
  </p>
  <h2>
   Attributes
  </h2>
  <p>
   None.  Clicking on a component supporting the Poke Tool, though, will
display that component's attributes.
